Welcome To The Board  

It is customary (And, out of respect to the Lab Members)
to have your real name listed somewhere in your post.

The JBL 2226H is a very versatile speaker. Meaning, it
can be used for a reflex, or horn-loaded enclosure.

It all depends on what kind of bass you are looking
for, and, what are the size requirements, for the enclosure.

Best Regards,

I would like to have horn loaded enclousures but correct me if i'm wrong i think horn loaded are better then reflex for this speaker.I need them for subwoofer so i want to get that sub bass sound from them as much as possible.I'm using Crown 1400csl amp for them i think that's ok again correct me if i'm wrong and i don't have size requirements thank's

Hello Igor.

As I mentioned in my previous post, the 2226 can be used
in a reflex or a horn. Its TS Parameters, are within the
crossroads of choice.

If you want sub bass, your looking along the lines of
the Lab Sub, in terms of size.

By you having only two of these drivers, you would be
better off with a reflex cabinet.

There are no 15 inch horn designs available that go
lower than 60 Hertz.

With A Reflex, you could get down to around, the low
40's with those speakers.

Of course, if you are up to the task, you can design
a 15 inch horn sub.

The Crown 1400 CSL is ruffly 500 watts @ 8 ohms, 750
watts @ 4 ohms. I'm guesing you are planning to run
one driver, on each channel of the amplier. Correct?

You can't Bridge it, for it won't handle 4 ohms in
Bridged Mode.

Look for a klipch design it looks like a vega e bin
but its really deep. I saw a couple of these in a dance club
they looked old but sounded great. I asked the guy running
the system and he said that they had 1X Gauss 15" in them
so your vented gap 2226 sould kick alot of butt in these
compared to the Gauss dino's. Est. 40x24x32 L,W,H
Good luck!

[Igor Mamuzic]

yes i would run one driver per channel on crown.Here i found something http://www.partsexpress.com/pdf/294-470b.pdf (but dont know  how good it is) take a look

1st off. You will be underpowering those 2226's. I have 4 of them loaded in scoops that I ran for years at 1000 watts each and they were very happy with that wattage.
I would also suggest you look for a pair of used EAW BH500's. They are a good match for those drivers.

Another option would be go to JBL's web site. They offer cab dimesions for their drivers as do most other major speaker companys.
Best of Luck

Hello Igor.

Here's a design that may work for your needs.

It would be best to contact the designer, for further
information. The horn was designed around the JBL
2226 H.

Can the 2226H s  go as low as 40hz in scoops ,  and with four together they must be pretty good .
Does the power handling of the driver also increase in scoops ??

cheers

Hello Igor! and welcome.

The 2226 design on my site-
http://www.geocities.com/xobt/jblhorn.html

That is just one of the designs. If you have a certain requirement i can model something up and CAD it

I just have a few questions
Boundarys- walls or on the ground
4 boxes you said each with 1 driver?
Power to be used?

Maximum size limit/volume
Low frequency extension vs Efficiency-whats important
eg lower F3 but 102db/1watt,or higher F3 and 109db/1watt

Im actually thinking of redesigning that horn to have a labhorn style of throat with wedge front chamber.
-Note that i havent built it yet

Cheers!
